Dakota Lithium Powerbox+ 135 Solar Generator

Designed as a waterproof and submersible mobile power station and solar generator for use in extreme environments, the Powerbox+ 135 is one battery to power many passions. Jump start a car with over 1,000 cold cranking amps (CCA) of engine starting power. Power your devices and smaller appliances with 135 amp hours (1,728 Wh) of deep cycle Dakota Lithium energy. Efficiently charge phones, laptops, camera equipment, TVs, monitors, portable fridges, medical devices, power tools, and more via the 2 AC wall plugs or the 6 USB ports. Connect jumper cables to the automotive grade battery posts to access up to 1,000 CCA of car engine starting power or use the waterproof binder posts to run high amp applications like 12V trolling motors. All in one waterproof lithium battery so light that it floats.

Inside the Powerbox+ 135 is the DL+ 12V 135 Ah dual purpose battery. Start your car, crank up the car audio, or run your trolling motor or other deep cycle electronics — this is one battery built to power many passions. Engineered with Lithium Iron Phosphate (LiFePO4) technology this battery has twice the power, half the weight, and lasts 4 times longer than a lead acid battery – providing exceptional lifetime value. Built for dual purpose performance the DL+ provides 1,000 cold cranking amps (CCA) and a high continuous discharge rate, making it a great choice for high amp draw applications like starting engines, car audio, heavy machinery, golf carts, or any electronics that require a lot of power at one time. In addition, the DL+ provides the same legendary deep cycle marine performance that Dakota Lithium batteries are known for, giving you lots of power for a long time. This is the most versatile Dakota Lithium battery, with the ability to both start engines, and power electronics. LiFePO4 charger included. Backed up by an 11 year warranty.



Dakota Lithium Powerbox+ 135 Specs

  • Waterproof Rating: IP67 Waterproof rating means this battery is submersible at a depth of 3 ft of water for 30 hour with no internal moisture.
  • Buoyancy: 12% of mass above waterline. PB135 is a waterproof battery so light that it floats
  • Case: Waterproof and submersible (IP67) ruggedized Powerbox+ 135 military spec plastic case with shock proof battery cradle
  • Storage Capacity: 135 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 135 amp hours. DL LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.
  • Voltage: 12.8 Volts (V)
  • Energy: 1,728 Watt-hours (Wh)
  • Terminals: Waterproof automotive binder posts for connecting trolling motors, jumper cables, or other high power applications while maintaining waterproof seal
  • Voltmeter & External USB Plugs: Waterproof voltmeter for monitoring the battery power level & external USB C & USB A for connecting devices while maintaining waterproof seal
  • DC to AC Inverter Included: 300 continuous, 600 watt peak DC to AC Inverter w 2 AC wall plugs + 4 USB plugs and smart power use display
  • Electronic Tray: Internal ballistic nylon bag with 3 zippered pockets for waterproof storage of personal electronics when box is sealed plus a removable, washable, anti-static silicone electronics tray for keeping personal electronics clean and safe while charging included
  • Battery Included: Dakota Lithium Plus 12V 135Ah Dual Purpose 1,000 CCA Battery included
  • Engine Starting Power: Lithium battery equivalent to 1,000 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive applications.
  • Size: 11.6”L x 12.1” W x 12.8” H (295mm x 307mm x 325mm)
  • Weight: 37.7 lbs (17.1 Kg). So light that it floats. 1/4-1/2 the weight of a normal car battery.
  • Lifecycles: Up to 80% capacity for 2,000 cycles in recommended conditions. The typical SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries.
  • Operating Temperature: Ideal for rugged & harsh environments. Much better than SLA or other lithium batteries. -20'F min, +150'F max optimal operating temps (battery performs well down to -20'F). Avoid charging below 32'F. Discharge cut off at - 20'F / -20'C. Charge cut off at 23'F / - 5'C. BMS high temp cut off at 167'F / 75'C. Internal heating allows for charging in temps down to -20F
  • Discharge: 100 A max continuous discharge, 750A max 2 second pulse, 650A max 5 sec pulse. The flat discharge voltage curve provides a 75% bigger capacity than a 60Ah SLA battery.
  • Charge: DL rapid charge technology allows for charging speeds of 60 minutes (135 Amps). Recommend for longest life 60A or less (1C), Max continuous 80A (1.5C). 14.4 V recommended, 15 V max, BMS protection from over charging will cut off at 15V. Included is a free 12V 10 Amp (A) LiFePO4 compatible charger that charges at the recommended 14.4 Volts
  • Internal Heating for Winter Use: Includes internal heating technology that allows for charging in temperatures down to -20F
  • Certifications: All DL batteries are UN 38 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Meets all US & International regulations for air, ground, train, & marine transport.
  • Protection: Contains a high discharge capable circuit that handles cell balancing, low voltage cutoff (10V) preventing over discharge, high voltage cutoff (15V) preventing over charging, short circuit protection and temperature protection for increased performance and longer life.
  • Dual Purpose Use: Multi-purpose use as a deep cycle battery and/or as a starter battery for starting gasoline engines.
  • Charger Included: 10A LiFePO4 charger included
